A plasma is a hot ionized gas consisting of approximately equal numbers of positively charged ions and negatively charged electrons. The characteristics of plasmas are significantly different from those of ordinary neutral gases so that plasmas are considered a distinct "fourth state of matter."

The practical application of KCL is to determine the amount of current flowing through individual electronic component in a circuit. Using that law we can manipulate current to the component by controlling resistance to it.

The KCL states that for a balanced network, the current coming at a node is equal to current outgoing. So, on a simple note, we can balance a given circuit by adjusting voltage and current so that at a selected node, the current if measured is zero because incoming current = outgoing current. So, by balancing we can calculate a no. of parameters from a circuit

Thehuman eye forms the image of an objectat its retina.

In human image forms in the retina

The lens focuses light through the vitreous humor, acleargel-like substance that fills the back of theeyeand supports the retina. The retina receives theimagethat the cornea focuses through theeye'sinternal lens and transforms thisimageinto electrical impulses thatarecarried by the optic nerve to the brain.

The image of the object formed by the eye lens is at the retina of the eye. The image formed on die retina is real and inverted. The image is sent to the brain with the help of the optic nerve.

Essential substances like glucose which were absorbed in the small intestine are reabsorbed ( by the tubules of nephron) so that they are not released out by the body in urine. Glucose is a common nutrient that is absorbed in the small intestine and reabsorbed by the kidney tubules.

Rate of liquid flow =(1/2*m*v^2)/tRate of flow =m/tRate of flow=dV/tRate of flow=dAL/t1/2* d*A*v *v^21/2 *dAv^3

Volume V = 67.2 litres of Helium at STP

ΔT = 15⁰K1 mole of an ideal gas occupies 22.4 litres at STP. So number of moles of Helium gas n = 67.2/22.4 = 3

we know that γ = ratio of specific heats for an ideal mono atomic gas = 5/3 C_p = heat capacity at constant pressure for a mono atomic gas = 5/2 R C_v = heat capacity at constant volume for a mono atomic gas = 3/2 R

Change in internal energy = n C_v ΔT = 3 * 3/2 * 8.31 J/mol/°K * 15°K = 560.925 Joules

There is no change in the volume and hence no work done in heating the gas by 15 deg.

Heat supplied = change in internal energy = 560.925 Joules

mercurybarometerin which the lower mercury surface is larger in area than the upper surface. The basic construction of acistern barometeris as follows: A glass tube 1 m in length, sealed at one end, is filled with mercury, and then inverted.

U= 50m/sg= -10m/s^2

The velocity at the highest point will be 0 m/sThus v=0

Height can be calculated by

2gs=v^2-u^2-20s= -2500s= 125m

Time :v= u+gt0=50-10t-50=-10tt= 5sec

I am not able to understand??

solid are heated by the mode ofconduction

HeatFlow inSolids.Heatflow insolidscan only happen when thosesolidsare in contact with one another. The process ofheatflow insolidsis called conduction. Conduction is where two objects in contact with one another transferheatbetween them due to a temperature difference, like the clothes from the dryer.

Positive lightning is particularly dangerous,because it frequentlystrikesaway from the rain core, either ahead or behind the thunderstorm. It canstrikeas far as 5 or 10 miles (8 or 16 kilometers) from the storm, in areas that most people do not consider to be a lightning-risk area.

A transistors current gain is given the Greek symbol of Beta, ( β ). As the emitter current for a common emitter configuration is defined as Ie = Ic + Ib, the ratio of Ic/Ie is called Alpha, given the Greek symbol of α. Note: that the value of Alpha will always be less than unity.

The third law as stated by Newton is not just that the forces are equal and opposite but that they also have the same line of action.That action and reaction have the same line of action implies conservation of angular momentum (for isolated systems). This is quite easy to show.

pentagon is based in angular momentumA pentagon in the plane with fixed side-lengths has a two-dimensional shape space. Considering the pentagon as a mechanical system with point masses at the corners we answer the question of how much the pentagon can rotate with zero angular momentum.

Torque is a measure of how much a force acting on an object causes that object to rotate.

neutron representation is ₀n¹

so, after charge and mass balance The equation becomes ₅B¹⁰ + ₀n¹ ==> ₂α⁴ + ₃x⁷

that is option D

?

😢🤔

option D is correct.. the answer is the particle having charge 3 and mass 7...

option D is matching only.

Without specifying the proportions, all we know is that it will be somewhere between 1d and 3d.

If, at a guess, the proportions are supposed to be equal in volume, then it will be:

(1d + 2d + 3d) / 3 = 6d / 3 = 2d

If they are supposed to be equal in mass, then it would be:

1 + 1 + 1 / (1/1d + 1/2d + 1/3d) = 3 / (11/6d) = 18d/11

f=0 is correct answer

a) Friction is due to the weight of the object and the coefficient of friction. The coefficient is a number that tells you how much friction you would expect between pairs of surfaces.Force friction= weight x coefficient of frictionSo as the weight increases so does the amount of friction.

Ans :- Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction: Dry friction is a force that opposes the relative lateral motion of two solid surfaces in contact.

A force between two surfacesthat prevents thosesurfacesfrom sliding or slipping across each other. This is the sameforcethat allows you to accelerate forward when you run.

A non contact force is a force which acts on an object without coming physically in contact with it. In contrast, the contact force is a force applied to a body by another body that is in conract wjth it

1. Distance force is something you can not see like the wind blowing throw the sky it's like almost invisible. When any two substances some in contact and create something called friction. It's a force that pulls together all things you can touch. Gravity is a force that keeps the human body on the Earth.2.

A non-contact force is a force which acts on an object without coming physically in contact with it. The most familiar example of a non-contact force is gravity, which confers weight. In contrast a contact force is a force applied to a body by another body that is in contact with it.

1.An electric heater works on the principle of the heating effect of electric current. The heating element of the heater blocks the electric current and does not let it pass. So the heating element gets heated and glows due the heat. It has high resistivity , so it does not melt. The cord of the electric heater is a good conductor of electricity so it does not get heated up and also does not glow.

2.Yes it is true that coal and petroleum are produced by the degradation of biomass but we need to conserve them because it takes millions of years for this biomass to get converted into coal and petroleum . If we use these resources unnecessarily and wasting them then our next generations will not be able to use these resources moment of time these resources might be getting formed and thus will not be available to our next generation
